Answer:

D: (2, -3)

Step-by-step explanation:

We have;

y = 3x - 9 - - - (1)

y = -2x + 1 - - - (2)

By substitution method, from eq 1, we see that: y = 3x - 9

Thus,let's put 3x - 9 for y in eq 2;

3x - 9 = -2x + 1

Rearranging to get;

3x + 2x = 9 + 1

5x = 10

x = 10/5

x = 2

Thus;

y = 3(2) - 9

y = 6 - 9

y = -3

Thus,the solution (x, y) = (2, - 3)

Answer:

Infinient amount buddy. They are infinent amounts of polygons, as a polygon is a shape with more then 3 sides and closed. This means as long as a number is bigger then 3, there will be a shape for it, so infinent sides

Step-by-step explanation:

Answer:

for the first 9000 $ tax rate is 10%

so tax = 10% of 9000 = 900

rest of the amount = 35000-9000 =26000

tax rate is 16%

tax on 26000 =  16% of 26000 = 3900

total tax Debra has to pay for last year = 900 + 3900 = $4800

Step-by-step explanation:

Answer:

900+3900=$4800

Answer:

y=2x

Step-by-step explanation:

The line passes through the origin, so the y-intercept = 0

the slope m can be found with

m = (y2-y1)/(x2-x1) = (8-2)/(2-1) = 2

Therefore the equation of the line is

y = 2x + 0 = 2x

Answer:

A) y = 2x

Step-by-step explanation:

We are given the points (4,8) and (1,2).

[tex]\frac{2-8}{1-4}=\frac{-6}{-3}=\frac{6}{3}=\boxed{2}[/tex]

The line passes through the origin.

Option A should be correct.

[tex] \frac{r}{4} = 10 - 2[/tex]

Answer:

Using a formula, the standard error is: 0.052

Using bootstrap, the standard error is: 0.050

Comparison:

The calculated standard error using the formula is greater than the standard error using bootstrap

Step-by-step explanation:

Given

Sample A                          Sample B

[tex]x_A = 30[/tex]                              [tex]x_B = 50[/tex]

[tex]n_A = 100[/tex]                             [tex]n_B =250[/tex]

Solving (a): Standard error using formula

First, calculate the proportion of A

[tex]p_A = \frac{x_A}{n_A}[/tex]

[tex]p_A = \frac{30}{100}[/tex]

[tex]p_A = 0.30[/tex]

The proportion of B

[tex]p_B = \frac{x_B}{n_B}[/tex]

[tex]p_B = \frac{50}{250}[/tex]

[tex]p_B = 0.20[/tex]

The standard error is:

[tex]SE_{p_A-p_B} = \sqrt{\frac{p_A * (1 - p_A)}{n_A} + \frac{p_A * (1 - p_B)}{n_B}}[/tex]

[tex]SE_{p_A-p_B} = \sqrt{\frac{0.30 * (1 - 0.30)}{100} + \frac{0.20* (1 - 0.20)}{250}}[/tex]

[tex]SE_{p_A-p_B} = \sqrt{\frac{0.30 * 0.70}{100} + \frac{0.20* 0.80}{250}}[/tex]

[tex]SE_{p_A-p_B} = \sqrt{\frac{0.21}{100} + \frac{0.16}{250}}[/tex]

[tex]SE_{p_A-p_B} = \sqrt{0.0021+ 0.00064}[/tex]

[tex]SE_{p_A-p_B} = \sqrt{0.00274}[/tex]

[tex]SE_{p_A-p_B} = 0.052[/tex]

Solving (a): Standard error using bootstrapping.

Following the below steps.

From the randomization sample, we have:

Sample A                          Sample B

[tex]x_A = 23[/tex]                              [tex]x_B = 57[/tex]

[tex]n_A = 100[/tex]                             [tex]n_B =250[/tex]

[tex]p_A = 0.230[/tex]                          [tex]p_A = 0.228[/tex]

So, we have:

[tex]SE_{p_A-p_B} = \sqrt{\frac{p_A * (1 - p_A)}{n_A} + \frac{p_A * (1 - p_B)}{n_B}}[/tex]

[tex]SE_{p_A-p_B} = \sqrt{\frac{0.23 * (1 - 0.23)}{100} + \frac{0.228* (1 - 0.228)}{250}}[/tex]

[tex]SE_{p_A-p_B} = \sqrt{\frac{0.1771}{100} + \frac{0.176016}{250}}[/tex]

[tex]SE_{p_A-p_B} = \sqrt{0.001771 + 0.000704064}[/tex]

[tex]SE_{p_A-p_B} = \sqrt{0.002475064}[/tex]

[tex]SE_{p_A-p_B} = 0.050[/tex]

Answer: The answer is D

Step-by-step explanation:

You add z to the other side then it will cancel out which then it would be (w+z)  and then you times it by 2 by both sides which would be 2(w+z) and then you would subtract x from both sides which will be 2(w+z)-x

Hopefully this helps

Orthocenter is the best term to describes point R in the triangle UVW.

" Orthocenter is defined as intersecting point of the altitudes of the sides of the acute angle triangle."

According to the given figure,

In triangle UVW,

Ray VR perpendicular to UW

Ray UR perpendicular to VW

Ray WR perpendicular to UV

Altitudes of side  ( UV , VW, and WU) of triangle UVW intersect at

point R.

As per the definition of orthocenter , point R represents orthocenter.

Hence, orthocenter is the best term to describes point R in the triangle UVW.

Answer:

3.417

Kindly check explanation

Step-by-step explanation:

X : $7 ; $20 ; $0

Sample space for the sum of two die rolls :

Probability of obtaining a sum of 5 or 6 ;

P(sum of 5 or 6) = 9/36 = 1/4

Probability of obtaining a sum of 2 or 3 ;

P(Sum of 2 or 3) = 3/36 = 1/12

Probability of obtaining a sum of other Tha 2,3, 5 or 6 ; = 24/ 36 = 2/3

The probability distribution :

X _____ 0 _______ 7 _____ 20

P(x) ___ 2/3 _____ 1/4 ____ 1/12

Expected value of the game ; E(X) ;

E(X) = Σx*p(x)

E(X) = (0*2/3) + (7*1/4) + (20*1/12)

E(X) = 0 + 1.75 + 1.6667

E(X) = 3.417

This means that if the game is paid for a long time, the mean or expected winning will be ; $3.417

If game has to be played with $6 ; then to determine if it is a good idea to play the game on a long run, we calculate the payoff ;

The payoff is :

Expected value - playing cost

$3.417 - $6  = - $2.583

Since payoff is negative, we can conclude that it is not a good idea to play the game in the long run : as the expected value is lesser than the playing fee.

Answer:

Alex is correct.

Step-by-step explanation:

In order for Alex to get to $0, meaning he owes the bank nothing, he has to add 155 dollars to negative 155 dollars, because this means he has no debt left. The absolute value of -155 is 155 and if Alex pays the 155 dollars, he will not have to pay anything else to the bank.
